Current Direction and Velocity Measurements Using GPS Receivers Mounted on Floats at Tom Bevill Lock and Dam

Abstract

To present the hardware and methodology for collecting current direction and velocity data using Global Positioning System (GPS) receivers mounted on floats. This method has been used on several projects by the U.S. Army Engineer Research and Development Center (ERDC) Principal Investigators to map the currents in both open river conditions and near locks and dams. This method has proved to be a quick and inexpensive method to map currents for verification of hydraulic models or investigation of existing conditions. The information herein was collected at Tom Bevill Lock and Dam on the Tennessee Tombigbee Waterway as part of the Monitoring Completed Navigation Projects (MCNP) Program.
